Answer:
so her bill was 10.99 and she added 15% for the tip, how much is 15% of 10.99?
well, if we take the 10.99 to be the 100%, let's see how much is 15% of that.10.99 + x.
Step-by-step explanation:
Step-by-step explanation:
AC = 20
AB = 18
BC² = 20²+ 18² -2•20•18•cos(52°)
BC² = 280.72
BC = √280.72
BC ≈ 16.75
Angle C:
18² = 20² + 16.75² -2•20•16.75•cos(C)
324 = 400 + 280.72 -670•cos(C)
cos(C) = -356.72/-670
cos(C) ≈ 0.53
acos(0.53) = C
C = 57.8°
Angle B:
180-52-57.8 = 70.2°
Answer:
-1.2
Step-by-step explanation:
I think i know what your asking. not sure if this is right. I'm sorry if it isn't..
A) height of a cylinder: 7.96
b) height of come: 1.43
c) radius of cylinder: 4.07
d) radius of cone: 2.82
e) radius of sphere: 9
use the following formulas to solve:
a) volume= (pi)(radius^2)(height) and substitute what’s given
b) (1/3)(pi)(radius^2)(height) and substitute the given
c) volume= (pi)(radius^2)(height) and substitute what’s given
d) (1/3)(pi)(radius^2)(height) and substitute the given
e) volume= (4/3)(pi)(radius^2) and substitute the given
Answer:
well, both numbers are odd, so their sum will be even.
2 is the smallest prime divisor.
